摘要
针对镇城底矿主斜井表土及风化基岩段复杂的地质情况,提出了钢棚网喷支护的新方案,现场应用实践证明,钢棚网喷支护施工进度快、施工安全、支护效果好,节约成本,为企业创造了1300万元的经济效益。钢棚网喷支护在镇城底矿主斜井支护工程中的成功应用,为类似地质条件的斜井支护提供了技术参考。
In view of the complex geological situation of the main inclined shaft topsoil and weathered bedrock section of Zhenchengdi Mine,a new scheme of steel shed net shotcrete support is put forward.the field application practice proves that the construction progress of steel shed net shotcrete support is fast,the construction safety,the support effect is good,and the cost is saved,which creates 13 million yuan economic benefit for the enterprise.The steel shed net shotcrete support has been successfully applied in the main inclined shaft support project of Zhenchengdi Mine,which provides a technical reference for inclined shaft support with similar geological conditions.
